So the latest GG alum to sign up to return to the Upper East Side is none other than schemer Poppy Lifton, played by actress Tamara Feldman. Poppy was last seen attempting to con Serena (Blake Lively) and her family out of money through a Ponzi scheme with the help of her equally manipulative boyfriend Gabriel, played by The Social Network‘s Armie Hammer, only to be revealed by Georgina (Michelle Trachtenberg). A source tells EW that this time, “Poppy shows up in a surprising context to tangle with a new target.”
